I came across this wonderful artefact yesterday while rubber-necking round Chatsworth in Derbyshire with my brother. The label says it is a copy of another shield – probably German I think, but I didn't make a note of the maker.
By the way, if you are studying this part of the Iliad you might like to read this Auden poem.
Another interpretation of the shield can be found here.
